Best Basement Waterproofing Company in Windsor - Leaky Basement Repair

AquaBoss offers expert basement waterproofing services in Windsor to eliminate leaks, deter mold growth, and safeguard foundations from structural harm.

Are You Experiencing Water, Dampness, or Musty Odors in Your Basement? 

Many Windsor homes develop basement moisture due to cracks in the foundation, porous concrete, or floor joint leaks.
These issues lead to mold, poor air quality, and hidden structural damage.
At AquaBoss, we address this using two main systems:

  • Interior waterproofing collects water after it enters using drainage channels, sump pumps, and vapor sealants.
  • Exterior waterproofing prevents groundwater from reaching the walls by adding membranes, drain boards, and weeping tile.

These solutions are designed specifically for Windsor’s wet climate, clay soil, and seasonal water pressure.

Each system is tailored to Windsor’s riverside climate, ensuring durability against the humidity from the Detroit River and the city's diverse building styles—resulting in a dry, secure, and enduring basement. If you notice signs like musty smells or damp floors, book your free basement inspection today.

Comprehensive Basement Waterproofing Solutions in Windsor

AquaBoss delivers long-term basement waterproofing systems and structural protection tailored to Windsor’s conditions. Water can enter below the floor, through cracks, or at the wall base—each needing a specific solution. Our interior systems use sump pits, drain channels, and sealants to handle active leaks. Our exterior systems prevent future damage with excavation-based waterproofing built for Windsor’s clay-heavy soil and high humidity near the Detroit River. Every installation is engineered to withstand freeze-thaw cycles and water pressure while maintaining structural integrity and long-term dryness.

Why Windsor Homeowners Trust Our Basement Waterproofing Company

Licensed technicians at AquaBoss handle all basement waterproofing projects—never subcontractors. Our dedicated team is trained to address Windsor's unique challenges, including riverside humidity, soil pressure, and older foundation types. We hold WSIB certification, BBB accreditation, and full insurance to conduct drainage, crack sealing, and structural repairs in line with the Ontario Building Code. Every installation comes with transferable warranties and documentation suitable for insurance claims, resale, and future renovations.

Foundation Repair & Structural Protection Services  

Foundation repair services are essential for stabilizing homes with basement foundations that exhibit stress, cracks, or shifting. These problems often arise due to water infiltration, soil movement, or long-term settlement—particularly in older Windsor homes constructed with block or unreinforced concrete. Common issues include bowing walls, vertical cracks, sloped floors, and heaving slabs. 

At AquaBoss, we address these using techniques like epoxy injection, steel bracing, bench footings, or complete rebuilds when necessary. We begin by evaluating the foundation's load, water pressure surrounding the home, and soil movement. Then, we implement the appropriate long-term repair to prevent failure and safeguard your property's value. Windsor’s riverside location demands extra attention to hydrostatic pressure from the Detroit River, which can exacerbate these foundation issues.

How much does basement waterproofing cost in Windsor?

In Windsor, basement waterproofing expenses generally fall between $65 and $250 per linear foot, contingent on the chosen method, the extent of damage, and the condition of the foundation. Exterior solutions involving excavation are often pricier than interior drainage systems, particularly when dealing with deep foundations, sump pit installation, or structural repairs. 

At AquaBoss, we offer transparent pricing and comprehensive estimates. All costs encompass materials, labor, and warranties. No hidden fees. No unexpected upsells. Just straightforward answers from the beginning. Windsor’s riverside location demands epoxy-coated steel window wells to resist corrosion from Detroit River humidity.

Why Choose AquaBoss: We Offer the Best Basement Waterproofing Services in Windsor

Our Basement Waterproofing Process: Step-by-Step

At AquaBoss, we excel in basement waterproofing through a detailed, step-by-step approach. Our aim is to remove current leaks and prevent future moisture issues. Each stage is managed by skilled AquaBoss experts. The process includes inspection, system design, expert installation, and a concluding walkthrough. We utilize proven systems that adhere to the Ontario Building Code.

Step 1: Initial Moisture Inspection & Free Estimate

Initially, a certified waterproofing expert conducts a comprehensive evaluation of foundation walls, floor joints, drainage points, and humidity levels. We inspect for cracks, stains, efflorescence, mold signs, and sump failure indicators. You'll receive a written estimate outlining the scope, system type, pricing, and warranty details.

Step 2: Problem Diagnosis & Custom Plan

Next, we determine the underlying issue, whether it's hydrostatic pressure, surface pooling, or weeping tile failure. We then align it with the right solution. Your plan specifies if interior systems like sump pumps or vapor barriers are necessary. Sometimes, exterior excavation is needed. The plan also details project duration and compliance steps.

Step 3: Exterior Excavation or Interior Prep

For exterior waterproofing, we excavate the foundation wall to reveal and clean the surface. For interior solutions, we remove sections of the floor along perimeter walls. This allows us to install drainage channels and sump systems. The method depends on site access, soil depth, and wall type. Given Windsor's proximity to the Detroit River, we ensure our systems are robust against local humidity.

Step 4: Sealing, Crack Repair & System Installation

We implement multi-layer protection systems, including waterproof sheeting, drainage panels, and vapor shields to block humidity. Cracks are sealed using high-pressure epoxy or polyurethane injection. Sump pits, backwater valves, French drains, and weeping tiles are installed according to your custom plan.

Step 5: Backfilling, Site Clean-Up & Final Walkthrough

Exterior trenches are backfilled using clean fill and gravel. Interior sections are sealed and restored with top-quality waterproofing materials. Our team of waterproofing contractors conducts a final system test. We then review the completed work and provide documentation, which is beneficial for resale, insurance, or rebate programs.

Emergency Waterproofing & Post-Flood Response

Immediate action is crucial when water damage strikes. Basement flooding, sump pump malfunctions, or foundation leaks demand swift intervention. Such issues can lead to mold growth, foundation shifts, and costly repairs. 

AquaBoss offers same-day emergency waterproofing services throughout Windsor and its surrounding areas. Our certified teams arrive equipped with high-capacity pumps, dehumidifiers, sealants, and backup systems to stabilize affected sites. We provide documentation for emergency work that adheres to the Ontario Building Code and supports insurance claims and real estate disclosures.
